The hype and market valuations surrounding certain Internet stocks may lead one to conclude that the e-commerce race is over--or nearly so. Clearly, the Internet has caught traditional companies off guard, giving the more nimble dot coms a huge head start. But the race is far from over, says Mary Modahl, a vice president at Forrester Research. In Now or Never, she argues that we are in the first year of a "ten year transition in the way consumers shop and save," and that winning in the Internet space not only requires identifying consumers that are most likely to take their shopping online, but exploiting the new and different business models made possible by online commerce.
